Fire Dept. Capt. William Powers said the owners at 378 East. St. were downstairs watching the Bruins-Blackhawks hockey game just before 9 p.m., when they heard and felt a crack of lightning strike the house. They ran upstairs to find the attic area on fire and called 911.

Powers said the lightning struck the cockloft, which is the peak of the roof of the three-story structure. The fire burned through the roof, while water from pumper units left extensive damage on the lower floors. Powers estimated the damage at $200,000. There were no reported injuries.

Powers said companies were keeping a close eye on the storm when the East Street call came in. Lightning had already set off numerous alarms around town, and units were called to East Street from those locations.
